How good is an 8 inch Dobsonian telescope?
The Optical Tube In 8″ Traditional Quality-wise, they tend to be good. At f/5.9, there isn’t any coma like there is with faster scopes such as Sky-Watcher’s 10” and larger models, which have to have faster focal ratios to avoid being cumbersome and (at the largest sizes), requiring a tall ladder.
How portable is an 8 inch Dobsonian?
Portability – An 8″ manual or PushTo Dob weighs between 40 and 50 pounds. You can move that in two pieces, each about half the weight.
Is a Dobsonian good for viewing planets?
This means that large aperture and low-cost Dobsonians can often yield great planetary images. Their big aperture makes the images bright and contrasted, and provides extra resolving power to see surface detail.
What can you see with 8 inch telescope?
This size scope, however, is a bit small for deep-sky objects such as nebulae, star clusters, and galaxies. An 8-inch telescope (it doesn’t matter what type) will move you into a new dimension of viewing. The objects you see with an 8-inch scope will reveal more detail.
What can an 8 inch telescope see?
Are Dobsonian telescopes good for beginners?
Dobsonian telescopes They move up and down and twist on a rotating base, meaning they can point at any part of the sky. They are good value for money, ideal for beginners (including children from about 10), and great for observing the Moon, planets, and the brighter deep sky objects such as galaxies and nebulae.
What is the optimum magnification for an eight inch telescope?
As you get to 50x or 60x per inch of aperture, some faint extended deep space objects can become too dim to see. Thus, while an 8″ telescope is theoretically capable of a maximum useful deep space power of 480x (60 x 8), that much power is often usable only for splitting close binary stars.
What can I see with a 8 in Dobsonian telescope?
The Moon, the bright planets, bright binary stars, bright open and globular clusters, bright nebulae, and bright galaxies are all possible targets. Light pollution and nebula filters may be useful to some degree on certain nebulae.
Can I see the American flag on the Moon with a telescope?
Yes, the flag is still on the moon, but you can’t see it using a telescope. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it.
